Abstract

A color illumination system of the digital control type for use in a visual system of an industrial robot or the like is provided. This system comprises: image memories (11, 12, 13) to store the color data regarding illumination patterns of three primary colors of red, green, and blue; video signal producing circuits (21, 22, 23) each for reading out the data from the image memory and converting it to the video signal indicative of the illumination pattern; video projectors (31, 32, 33) each for projecting the light of the illumination pattern represented by the video signal onto an object to be illuminated; and a color camera (40) to pick up the object image. The image data picked up is processed by a computer system to produce the data which is stored into the image memories. With this illumination system, the scanning of the illumination patterns, and the change, adjustment, storage, and the like of the illumination patterns can be executed due to the softwares in accordance with the programs preliminary stored in the program memory in the computer system.
